Plataforma colaborativa multimídia para apoio ao diagnóstico de lesões bucais em ambientes de teleodontologia / Collaborative multimedia platform to support oral diagnosis in teledentistry environments

Este artigo tem por objetivo apresentar uma solução tecnológica desenvolvida para permitir atividades colaborativas de diagnóstico de lesões bucais em ambientes de Teleodontologia. Trata-se de uma plataforma totalmente baseada na web e que permite o gerenciamento e compartilhamento de imagens clínicas, radiográficas e histopatológicas, dispensando a instalação de qualquer programa adicional no computador do usuário. Como suporte à colaboração através do navegador, as ações efetuadas por um usuário são replicadas e visíveis ao outro usuário conectado, sendo possível a discussão e troca de informações sobre o caso através de chat e/ou áudiovideoconferência. Ferramentas de Telessaúde podem ofereçe diferentes oportunidades para assistência e educação em Odontologia. Ao permitir a visualização de diferentes aspectos da doença do paciente, a solução aqui apresentada tem potencial para viabilizar: (1) a troca de informações entre profissionais de saúde atuantes em distintos níveis de assistência e (2) a tutoria, à distância, nos diferentes níveis de formação (graduação, pós-graduação e educação continuada) (AU).

This paper presents a technological solution developed to enabling collaborative activities in Teledentistry environments. This is a platform composed by a set of tools for the management and sharing of clinical, radio graphic and histopathologic images. The proposed solution is fully web-based, requiring only a web browser installed; it's not necessary to install any other software on the user's computer. As collaboration support, the actions performed by a user with mouse and keyboard are replicated and visible to the other connected user. This toolkit allows the discussion of disease via chat and/or videoconferen ing. Telehealth's tools offer opportunities for assistance and education in Dentistry. By allowing realtime viewing and discussion of different aspects of a disease this technological solution has potential to facilitate: (1) exchange of information between health professionals at different levels of assistance and (2) distance tutoring at different levels of training (undergraduate, postgraduate and continuing education) (AU).

Recording and reenactment of collaborative diagnosis sessions using DICOM.

This paper presents a radiological collaborative tool capable of direct manipulation of Digital Imaging and Communications in Medicine (DICOM) images on both sides, and also recording and reenacting of a recorded session. A special collaborative application protocol formerly developed was extended and used as basis for the development of collaborative session recording and playback processes. The protocol is used today for real-time radiological meetings through the Internet. This new standard for collaborative sessions makes possible other uses for the protocol, such as asynchronous collaborative sessions, decision regulation, auditing, and educational applications. Experimental results are given which compare this protocol with other popular collaborative approaches. Comparison of these results shows that the proposed protocol performs much better than other approaches when run under controlled conditions.
